we have 2 equations that we can construct with this

OpenStudy (anonymous):

okay

OpenStudy (amistre64):

OpenStudy (anonymous):

okay

i think the answer is c

OpenStudy (amistre64):

A = 8 + 3B A-2B = -3 subtract one from the other to get A = 8 + 3B -A+2B = +3 --------------- 2B = 11 + 3B hmm, im getting B = -11 gotta chk to see that im reading it right to start with then

OpenStudy (amistre64):

4ties A is 8 more than .... so 4A = 8 + 3B A-2B = -3 4A = 8 + 3B -4A+8B = 12 ------------------ 8B = 20 + 3B thats better

OpenStudy (help_people):

@amistre64 srry, but just making sure this is c right?

OpenStudy (amistre64):

8B = 20 + 3B , solve for B

OpenStudy (help_people):

B=-3 is what I found am I correct?

OpenStudy (amistre64):

lets check and see 8B = 20 + 3B 8(-3) = 20 + 3(-3) -24 = 20 - 9 -24 = 11 nope, not going to work out is it

OpenStudy (help_people):

no

OpenStudy (help_people):

B=-1 maybe
